I sent about twenty photos for possible cover shots for the book for the publisher's consideration. [Among them was the photo of Cruden Bay later used as the cover for The Confidential Guide.]
The publisher chose the PGA West photo because he thought it showed all of the elements of a golf course that I had written about -- green, contour, bunkers, water, etc. -- and he thought it was a striking photo. I went with his judgment; it's the insides that mattered to me.
